Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Mapping drought tolerance using teosinte derived BC1F2 population of maize (Zea mays L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-08) Amarjeet Kumar; Singh, N.K.
    The present investigation was undertaken with wild progenitor teosinte (Z. mays ssp. parviglumis) and a maize inbred line DI-103.The 203 lines of BC1F2 mapping populations were phenotyped in two environmental conditions i.e. irrigated and moisture stress condition during the rabi season 2016-17 for twenty five morpho-physiological traits associated with drought tolerance. Phenotyped data were subjected to single marker analysis using forty three polymorphic markers. A total of 82 QTLs were identified to be associated with twenty four morpho-physiological traits except leaf firing. Out of 82 QTLs, four QTLs were found major QTLs and they were associated with anthesis silking interval, leaf rolling, plant height and thousand kernels weight. One major QTL linked with marker phi113 was detected for anthesis silking interval accounted for 11.79 per cent phenotypic variation. Marker umc1303 was linked with the major QTL responsible for 14.67 per cent phenotypic variation for leaf rolling .Two other minor QTLs were linked with the marker umc1444 and umc1156 explained 3.84 and 2.28 per cent of phenotypic variation for leaf rolling. The major QTL linked with marker umc1171 accounted for 13.25 per cent phenotypic variation for 1000 kernel weight. For the identification of drought tolerant lines rank score was used. The basis of ranking was the least reduction or positive increase between the performance of genotype in irrigated and moisture stress condition. Thirteen morpho-physiological traits from total of twenty five traits associated with the drought tolerance were used for identification of drought tolerant lines. Overall sum of rank scores for thirteen traits associated with drought tolerance revealed that AM-39 was the most drought tolerant genotype among all the 203 lines studied with total score of one hundred eight, followed by AM-64, AM-16, AM-42, and AM-102, whereas, AM-116 was the most susceptible with the least score of thirty four. The molecular characterization of five teosinte derived lines BC1 F4 reflected that the maximum allelic contribution lines from parent teosinte (Z. mays ssp. parviglumis) was found in the introgressed line AM-5 (53.4 per cent) followed by AM-12 (48.9 per cent), whereas, least contribution of 34.1 per cent was found in AM-7.The maximum contribution of 53.4 per cent from parent DI-103 was found in introgressed line AM-7 followed by AM-2 (42 per cent) and the least contribution was exhibited by AM-5 (27.3 per cent) followed by 33 per cent in the AM-12.The morphological characterization of teosinte derived BC1F4 lines exhibited that the yield contributing traits namely number of cobs ranged from 2 to 5. The maximum number of cob was found in AM-5 (5.00) followed by AM-2 (4.00). The largest variation in parents among all morphological traits was found in number cobs per plant i.e. inbred DI-103 (1.80), whereas, teosinte had 417 cobs. Ear length varied from 8.00 cm (AM-7) to 13.50 cm (AM-5). It is therefore, present findings might be concluded that the different morpho-physiological character associated with drought tolerance in maize and could be useful to combat the drought tolerance along with domestication of wild alleles.
